NAME

       gnutls_ia_extract_inner_secret - API function

SYNOPSIS

       #include <gnutls/extra.h>

       void gnutls_ia_extract_inner_secret(gnutls_session_t session, char * buffer);

ARGUMENTS

       gnutls_session_t session
                   is a gnutls_session_t structure.

       char * buffer
                   pre-allocated buffer to hold 48 bytes of inner secret.

DESCRIPTION

       Copy the 48 bytes large inner secret into the specified buffer

       This  function  is  typically  used  after the TLS/IA handshake has concluded.  The TLS/IA
       inner secret can be used as input to a PRF to derive session keys.  Do not use  the  inner
       secret  directly  as a session key, because for a resumed session that does not include an
       application phase, the inner secret will be identical to the inner secret in the  original
       session.   It  is important to include, for example, the client and server randomness when
       deriving a sesssion key from the inner secret.
